3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 Under a microscope, the straight line distance between the two farthest-sectional profiled section of the fiber in a distance. 3.2 One kind of filaments, porous coalescence spinneret filaments formed are twisted or untwisted filaments. Principle 4 4.1 Measurement transmission microscope diameter circular cross-section carbon fibers In the measured carbon fiber multifilament fiber bundle was cut into small pieces with a suitable wetting agent is dispersed on a glass slide, a transmission microscope or a projector measured by The amount of fiber diameter. 4.2 reflection (metallurgical) microscopy measurements of circular cross-section carbon fiber diameter or profiled carbon fiber equivalent diameter Multifilament carbon fiber under test with a suitable embedding medium embedding, and then polished to a cross-section perpendicular to multifilament fibers axes, throwing Light. Measurement of circular cross-section of the fiber on the reflection (metallographic) microscope or by diameter (surface) area-circle shape of profiled fiber and other amendments to strike Dimensional equivalent diameter. 4.3 microscopy measurements of carbon fiber multifilament number of fibers Multifilament carbon fiber to be tested is fixed to the embedding material, the cross-section multifilament polished, polished. Then by optical microscope cross-section multifilament Surface microscopic photography. With counting tool, a number of multifilament cross-section photographs the number of fibers.
